Internal wiring diagram
Fabricate cables using wire that can withstand repetitive bending. The maximum cable length is 30 m for RS-422
communication, however, the maximum cable length may need to be shortened due to the power supply voltage drop or the
specifications of linear encoder being used.
A connection example is shown below. For further information, contact the respective manufacturer of the product being used.

*2 Securely connect the shielded wire to the ground plate (plate) of the connector.
*3 Encoder cables that meet the following specifications are recommended when the current consumption of the linear encoder is 350 mA.
If the current consumption of the encoder is less than 350 mA, the number of paired connections can be decreased.
*4 When using an A/B/Z-phase differential output linear encoder, connect PSEL to the LG terminal.
